Apple executives will take the stage Tuesday at San Francisco’s Yerba Buena Center for the company’s annual pre-holidays gadget event.

In the past, Apple has used its fall event to provide an update on its iPods and computers, though last year the company threw the iPad and iPad Mini into the mix.

The Journal will have real-time updates and analysis from Tuesday’s gathering, which begins at 1 p.m. ET. Apple isn’t saying what the event entails, but here’s a guide on what you should expect.

What’s Likely

iPads: A new iPad with a standard 9.7-inch screen is almost guaranteed. Not only has it been a year since the last iPad was unveiled, but the Wall Street Journal earlier reported that a refreshed iPad would be entering mass production around this time. Apple has been working on a thinner, lighter version of the iPad, using a thin film instead of the glass found in existing models, based on information from the company’s parts suppliers.

iPad Mini: The biggest news would be an update to the iPad Mini, a device central to Apple’s strategy for the post-PC era. One of the primary changes expected is the inclusion of a “retina” high-density display similar to what the standard iPad and iPhone use. The display will be made by Samsung.

Mac Pro: The event won’t only cover mobile devices. Apple showed off a new cylindrical design for its desktop power-computer in June — to many oohs and ahhs. The device eschews the typical box-like monolithic-looking computer for a circular device about 1/4 the size. Apple previously said the device is arriving in the fall. (Here’s Apple’s video ad for the Mac Pro.)

OS X ‘Mavericks’: Apple is expected to provide a release date for the next version of its computer operating system, called Mavericks. While OS X steals less spotlight these days, it is still important to Apple given that it lays the foundation for iOS, the software that runs iPhones and iPads. Mavericks won’t be as dramatic a change as iOS 7, but Mac users will receive new features and refinements such as iCloud Keychain, a service for storing and synchronizing passwords.

A Corporate-Health Checkup: Questions swirl around the strong sales figures for the iPhone 5S and 5C, which were released just a month ago. The biggest question is how well the 5C is faring relative to its higher-end counterpart. Apple could use the event as an opportunity to shed some light on the data.

Not So Sure

iPods: Apple’s iPod business got a big boost last year when Apple made major changes to the form and function of the Nano, and updated the look of the Touch. Apple hasn’t been updating its iPods as frequently, so this year could be quiet on that front.

Apple TV: Rumors abound that Apple is prepping an update for its Apple TV set-top box. Initially, those rumors focused on the Sept. 10 iPhone event, and now they’ve shifted to this one. Apple did update the Apple TV’s software to support new functions like iTunes Radio, but there haven’t been indications more is imminently coming down the pike.

‘One More Thing’: Steve Jobs, the company’s co-founder who died in 2011, would utter this phrase before announcing some surprise new product. Apple has had fewer surprises over the years, but that doesn’t mean you should count one out.

Don’t Bet On It

Smartwatch or TV Set: The Journal has reported Apple is working on various new products for its lineup, including a smartwatch and a television set. Apple first showed off the iPhone a half year before the device hit store shelves. Apple showed its first iPad months before the official release. If Apple wanted to surprise, a watch or TV on Tuesday would certainly fit the bill.
